Does anyone know or use Batt-o-meter?

I saw this on the below link and think its such a great gadget to have. Basically, you just need to plug this in to your guitar's 1/4 inch jack input to find out how much juice your battery has got left without the need to remove them from your guitar.

Does anyone know if this or something similar is available locally? I just wanna check before i order it and ship it over.

no idea. i just use a regular battery meter before each guitar use to ensure battery has enough juice to last for the usage of that day.
